5 Section 3. Physical Installation 1A Temperature Sensing Considerations The control is designed for installation in climate controlled living spaces. It is recommended to place the unit in central locations with good circulation. Avoid exterior walls and areas near windows, doors, vents or concealed pipes or chimneys. NO YES NO NO 5 FEET [1.5 METERS] 1B Wireless Reception Considerations If enabling wireless, choose a mounting location that ensures adequate signal strength. A wireless device may have significantly different signal strengths if its position changes relative to other wireless devices. If the control shows poor signal strength, you may be able to improve the signal strength by moving the control a short distance in any direction. Wireless Considerations to Maximize Signal Strength: Do not mount the control more than 30 feet from the wireless router (through no more than three interior walls). Do not mount the control in areas where electromagnetic emissions from other devices, appliances or wiring can interfere with the control s communication. (i.e. wireless phones, security systems, wireless internet cameras) Do not mount the control in recessed areas, near metal objects, or near structures. (i.e. doors, appliances, entertainment centers or shelving units) Do not mount the control closer than 2 inches to any pipes, duct work, or other metal obstructions. Do not have metal obstructions, concrete or brick walls between the control and the wireless router it will be connected to. NOTE: See the User s Guide for wireless setup information (weather, multi-system and remote software update functionality). 2 Removing Sub-Base Wall Plate Remove sub-base plate from the control by inserting a small flat blade screwdriver into the notch at each of the four tabs as shown. Gently pry the sub-base away from the the control. NOTE: This tight fit is normal and ensures that the control is held securely to the sub-base when mounted on the wall. 18-HD64D1-3 5

6 3 Mounting Sub-Base to Wall Be sure wires are routed through the center of the base plate and are long enough to connect to terminals. Select and mark three holes. NOTE: The three hole locations indicated at right are recommended. The top location is an optional mounting screw location. A level may be used to ensure professional appearance. Optional Hole Three (3) Recommended Screw Locations 4A Mounting to Studs 4B Attach base to wall using 3 screws provided. The locations indicated provide the most secure mounting and are recommended. NOTE: Since moderate force is required when removing the control from the sub-base, the sub-base must be securely attached to the wall. Do not overtighten screws to avoid damaging the sub-base. Mounting to Drywall If mounting to drywall, supplied SnapSkru anchors must be used to mount the control sub-base to the wall. These anchors will ensure that the control is adequately supported. NOTE: Since moderate force is required when removing the control from the sub-base, a firmly mounted sub-base is essential. 1) Press tip of SnapSkru anchor into drywall using #2 Phillips screwdriver or screw gun. Drive anchor clockwise into drywall until anchor stops flush with wall. 2) Place sub-base over anchor and insert screw. 3) Tighten screw flush with subbase. Screw pops open anchor, locking anchor on wall. Do not overtighten screws to avoid damaging the sub-base HD64D1-3

7 Section 4. Wiring! WARNING LIVE ELECTRICAL COMPONENTS! During installation, testing, servicing, and troubleshooting of this product, it may be necessary to work with live electrical components. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.! CAUTION CAUTION: EQUIPMENT DAMAGE HAZARD - Improper wiring can lead to equipment damage. Follow the terminal connection information carefully to ensure the control is wired properly. After wires are secure, bare wires MUST NOT touch each other. See the Field Wiring Diagrams for specific system applications. NOTE: The maximum total cable length for the entire communicating system is 500 feet 18 AWG. The maximum distance of any single cable from a transformer is 250 feet 18 AWG. NOTE: Use 18-gauge color-coded thermostat cable for proper wiring. Shielded cable is not typically required. Keep this wiring at least one foot away from large inductive loads such as Electronic Air Cleaners, motors, line starters, lighting ballasts and large distribution panels. Failure to follow these wiring practices may introduce electrical interference (noise) which can cause erratic system operation. All unused thermostat wire to be grounded at indoor unit chassis ground only. Shielded cable may be required if the above wiring guidelines cannot be met. Ground only one end of the shield to the system chassis. 5 Power Connections The control is powered via 24 VAC from the indoor unit. On every application, 24VAC loads should be reviewed to be sure the indoor unit power transformer is adequately sized. The ComfortLink II control draws approximately 4VA more than the typical communicating control. 6 Connect Wiring Connect wiring to terminals as shown. Route wiring within the plastic channel as shown so that it does not interfere with control when reinstalling. Do not overlap wires. D R B Optional Connections Terminal Description RS Remote Sensor RS Remote Sensor ODT Outdoor Temperature Sensor ODT Outdoor Temperature Sensor Plug the opening with non-flammable insulation to prevent drafts from affecting the control. Control Connections Terminal Description D Data R 24 VAC (hot) B 24 VAC (common) 7 Replace Control Replace unit flat onto sub-base being careful to align unit correctly with the sub-base before applying force. Control should fit snug and not rock when properly installed. Check wire routing if control is unstable. 18-HD64D1-3 7

13 Section 6. Advanced Features Feature 1-Touch Presets Aggressive Recovery Air Cleaner Mode Alert Indication Backlight Blower On / Off Delays Brightness Calibration Control Response Rate Customizable Home Screen Description The 1-Touch Presets allows for an immediate change to the setpoint status. Set the desired temperature for the three status modes (Home, Away & Sleep). The control will remain in the selected mode until another mode is selected or the program reaches a new schedule period. Aggressive Recovery: This option disables the 10 minute inhibit anytime the control sees more than a 2 change (such as moving from one program time frame to another). This applies to heating & cooling modes. Heating Aggressive Recovery: This option disables the 10 minute inhibit based on outdoor temperature in heating mode only. The value for outdoor temperature can be set from Heating Aggressive Recovery can only be enabled if Aggressive Recovery is disabled. There is a 10 minute inhibit period between first and second stage compressor as well as compressor heating & supplemental strip heat. This 10 minute inhibit period minimizes the cycling of higher capacity request due to drafts around the control or marginal load conditions. There are three options when setting the Air Cleaner Mode: Auto--the air cleaner will run whenever the blower is running. Quick Clean--the control will energize the air cleaner at 100% output and blower at 100% air flow for a 3-hour run cycle. Allergy Clean--the control will energize the air cleaner at 100% output and blower at 100% air flow for a 24-hour cycle. System alerts will be indicated on the home screen of the control with two options: Close or Dealer Contact Information. Selecting Dealer Contact Information will display the dealer screen. Selecting the Close option will move the alert to the top right corner of the home screen. Pressing the icon button in the top right corner of the screen will recall the alert to the home screen. All alerts will remain until resolved. Critical Alert indicates the loss of heating or cooling operation. Only critical alerts will be displayed on the home screen. These alerts will flash red when closed and moved to the top right corner of the control. Major Alerts indicates the loss of system functionality, but the system is still operational. Major alerts will be displayed as a solid yellow icon in the upper right corner of the control. The backlight of the control will increase anytime the screen is pressed (active mode) and dim after a time period of non-activity (standby mode). This timeout period between active mode and standby mode can be customized from 5 60 seconds. Blower on / off profiles can be set independently for heating and cooling modes. There are blower delays specific for variable speed, non variable speed and hydronic heat applications. The brightness of the screen can be customized for viewing preferences. Screen brightness can be set for daytime and nighttime modes. The Ambient Light Setting icon sets the amount of room light required to shift the display between daytime and nighttime settings. The sensors (indoor, remote and outdoor) can be individually calibrated for temperature and humidity. The indoor sensors may be calibrated to plus or minus 5 or 5% humidity in increments of 1. The outdoor sensor may be calibrated to plus or minus 10 in 1 increments. This feature changes the response rate of the control. Selecting a faster response rate will maintain a tighter tolerance of indoor temperatures, but increases the cycling of the system. Options such as screen brightness, screen savers, background colors, screen calibration and customized shortcuts can all be modified to create a personalized home screen. 18-HD64D1-3 13

14 Feature Cycle Rate Dealer Information Dehumidification Diagnostics Dual Fuel Options Emergency Heat Equipment List Fan Options Help Screens History Runtime Description The cycle rate affects the cycle time of the system. With a 50% load value, a cycle rate of 3 will allow the system to run for 10 minutes and be off for 10 minutes; completing 3 cycles in one hour. A cycle rate of 5 would allow the system to cycle on and off at 6 minute intervals. The higher the cycle rate, the more often the system turns on and off. The actual amount of time the system will be on or off will be reflective in the load value of the home. Higher load value demands will increase system run time and decrease system off time. Lower load value demands will decrease system run time and increase system off time. Dealer contact information, including name, address, website and multiple phone numbers may be entered. In addition, a dealer logo (which must be named dealer.jpg) can be uploaded through the use of an SD card. File size should not exceed 3 MB. There are two requirements before dehumidification is enabled: Dehumidification must be enabled through the Installer Setup. The indoor relative humidity must be above the desired setpoint. The system will take the following actions once this condition is met: The blower will reduce air flow proportional to the amount of RH error. The control evaluates the percentage of humidity error and how long the error has existed to determine the amount of air flow reduction, up to 30% reduction. If overcooling is enabled, the control will engage a 1 degree of overcooling for each 10% of RH error. A maximum amount of overcooling can be configured to 1, 2 or 3 degrees. Fan off delays will be eliminated. Smart Continuous Fan Continuous fan operation will be interrupted when indoor relative humidity exceeds desired humidity setpoint. A humidity icon will be displayed along with the fan icon to indicate that blower on options have been disabled due to high humidity conditions. Smart Continuous Fan will not interrupt the fan circulate mode. Diagnostics are displayed as current alerts (what is currently happening in the system) and alert history (what has occurred in the past, but are no longer present). The alert screen describes the alert, when the alert happened, the severity level of the alert as well as a problem description and possible causes to assist with troubleshooting. Up to the last 30 days are displayed. The change over from heat pump to furnace can be set based on three options: Comfort This is strictly based on indoor temperature demand. The furnace will take over when the heat pump can no longer maintain the indoor heating demand. Operating Cost The HSPF of the heat pump and AFUE of the furnace must be entered along with cost of electricity and fuel. The control calculates an economic balance point for system change over. Outdoor Temperature The changeover from heat pump to furnace is based on outdoor temperature which can be set from 0 70 (thermal balance point). The furnace will take over anytime the HP is unable to maintain indoor temperature, regardless of the dual fuel option chosen. The heat pump will be disabled and the furnace / heat strips are enabled any time the control is set to Emergency Heat. This lists the model and serial number for all communicating components. The model and serial numbers for non communicating components can be manually entered. There are three options available for blower operation: Auto the blower runs when there is a call for cooling or heating. On the blower will run continually with a fan only call. The continuous fan speed for variable speed motors can be adjusted from 35% 100%. A call for heating or cooling will supersede a fan only call and the blower will run at a speed that matches the staging of the equipment. Circulate this provides all the features of fan on, but the blower will only run a percentage of the time when there is no call for heating or cooling. The blower can be set to circulate from minutes of every hour. The bottom left corner of all screens has a Help icon with a question mark. This icon provides assistance for the screen that is currently being displayed. Screens that are self explanatory will not list additional help. Pressing the Help icon on these screens will display No additional help available. The History Runtime screen provides information on system run time in comparison to the indoor and outdoor temperatures (average indoor along with the high & low outdoor temps). This history can be displayed on a weekly or monthly basis HD64D1-3

15 Feature History Screen Humidification Installer Setup Load Value Lockouts Multi Systems Photo Album Reminder Screens Restore Runtime History Description The History Screen provides system cycle information. Cycle counts and run time can be viewed for first stage and second stage compressor operation, W1 & W2 heating and defrost cycles. This information can be viewed in a 24 hour, 1 week or 2 week period. There are two options available for humidification: Indoor RH setpoint this controls the humidifier based on the desired indoor humidity setpoint (options from 10% 45%). Frost Control setpoint--the control references the outdoor temperature and indoor environment to calculate the risk of frost or condensation on interior walls and windows. A scale of 0 to 10 allows for customized settings based on the insulation properties of the home. A higher number may be selected for well insulated homes, whereas a lower number should be selected on poorly insulated homes. A lower number should be utilized if condensation is observed. There are two control options for enabling humidification: Humidification with an active call for heat. Humidification without an active call for heat (control energizes blower and humidifier). Humidification is only available when in the heating mode (or in the auto mode when the last call was for heating). A 60 second minimum blower off delay is enforced if steam humidification is selected. There are two categories for Installer Setup. Standard this is the basic system settings such as heat pump or cooling only, single or multi stage, compressor type, etc. This is the basic system set up that is self discovered in communicating mode, but requires manual input when using a Relay Panel for 24 volt configurations. Advanced this provides advanced configuration of the system such as cycles per hour, minimum run times, humidification and dehumidification setpoints, blower delays and temperature lockouts to name a few of the customizable features in this set up. Load Value is a numerical representation of the needed capacity to satisfy the setpoint. Proportional (distance from setpoint) error plus integral (time away from setpoint) error is used to calculate load value. System lockouts will disable a certain function of the system under specific outdoor temperatures: Compressor Heating Lockout will lockout all compressor operation below a set outdoor temperature (from 5 70 ). This value must be set lower than the auxiliary heat lockout. Auxiliary Heating Lockout will lock out auxiliary heat stages above a set outdoor temperature (from ). This value must be set higher than the compressor heating lockout. Defrost Heater Balance Point for W1, W2 & W3 will lock out specific auxiliary heat stages when above a set outdoor temperature. (W1 setpoint is from 40 55, W2 & W3 setpoints are from 5 55 ). This feature does not apply to dual fuel systems. Compressor Cooling First Stage Lockout will lock out the first stage compressor above a set outdoor temperature. (from ) Compressor Heating First Stage Lockout will lock out the first stage compressor below a set outdoor temperature. (from 0 50 ) Furnace First Stage Heating Lockout will lock out first stage furnace operation below a set outdoor temperature. (from ) First stage lockouts are not available with zoning. Multiple controls that manage individual systems can be linked. Multiple systems can be managed from any control location. A wireless home network is required for multi system functionality. Allows the customization of a photo album screen saver. An SD card is required to view the pictures. Photos may be in.jpg,.jpeg,.bmp,.png, or.gif file formats and must be smaller than 3 MB each. Reminders can be set for filters, UV lamps, humidifier pads, and various other service reminders. There are three levels of restore: Restore from the Setting Screen this restores all personal configurations, such as program schedules and home screen customization to their default setting. Reset Advanced Options from the Install Set Up screen this restores all the advanced set up selections such as system lockouts, accessories, air flow and comfort options to their default setting. Restore Equipment Default this restores the control to its out of the box condition. All settings will be set to their factory default condition. The History Runtime screen provides information on system run time in comparison to the indoor and outdoor temperatures (average indoor along with the high & low outdoor temps). This history is displayed on a weekly or monthly basis. 18-HD64D1-3 15

16 Feature Scheduling Screen Cleaning Mode Screen Layout SD Card Logging Security Setpoint Dead Band Software Updates Stage Inhibit System Report System Status System Test Technician Access Screens Vacation Mode Warm Air Discharge Weather Description Allows for 7 day programming with one to six scheduled time periods per day. There are two options available for setting a schedule: Guided Setup a step by step interactive process for setting up a schedule. Manual Setup a direct modification to an existing schedule which skips the interactive set up wizard from the guided set up. Scheduling is not required. The control can operate as a non programmable control. The Clean Screen Mode creates a 30 second screen lockout. The screen can be touched and cleaned without changing settings. There is an icon Press and Hold to Exit which will exit this mode if necessary--eliminating the 30 second lock out. The Screen Layout icon allows for customization of what is displayed on the home screen. The control has the ability to log all information to a SD Card. A typical 24 hour log will consist of 12 to 20 megabytes of information. The control will overwrite the oldest data once the card becomes full. Security initiates a keypad lockout. The control can only be accessed by a four digit pass code which can be configured in two different formats: Pin Lock: When the Pin Lock is selected, the control is completely locked. The user will need to enter a four digit password to change any setting (the default is 1234 ). Guest mode: The enabling of this mode allows a guest to change the temperature up to 5 in either direction from setpoint and access to the weather, but cannot change the mode or any customized settings. This sets the temperature band between heating and cooling setpoints while in the auto mode. The control is field software upgradable. Insert a SD card and press the Software Update icon, and updates will begin automatically. To prevent the next stage of capacity from being initialized, when the current capacity stage will satisfy the load a stage inhibit function is utilized. The System Report Screen provides a real time in depth look at operating conditions. While similar to the System Status screen, the system report adds additional information for service technicians. The System Status screen shows the snapshot of what the system is doing; including system mode, air flow percentage and reminders. The System Test feature allows a technician to lock the system into a particular mode of operation for up to 30 minutes. The Technician Access icon has a 5 second hold delay to enter the technician service screens. After this 5 second hold delay, the technician will see a Caution! screen noting that only a trained HVAC technician should proceed into this area. Through an interactive calendar, pick the date, time and temperature to begin and end a vacation set back period. Enabling Warm Air Discharge will reduce the variable speed blower air flow by 20% when in compressor heating operation. Warm air discharge only applies to compressor heating and is disabled when hydronic, fossil fuel or electrical heat (including supplement heat) modes are activated. The Weather feature displays the outdoor temperature, 5-day forecast and local Doppler radar. The weather screen is available once Wireless Service to the internet and Remote Services are enabled HD64D1-3
